The rod chamber of hydraulic cylinder does not use any control valve, and rodless cavity carries out pressure maintaining, second hydraulic cylinder and third using hydraulic control one-way valve
The rod chamber of hydraulic cylinder carries out pressure maintaining using hydraulic control one-way valve using the valve pilot control that contends with, rodless cavity, so that transport raceway
Entire sequentially-operating circuit can it is lower in pressure and without it is automatically controlled in the case where carry out sequentially-operating, reduce electrical control at
This, after the completion of sequentially-operating, does not need manual ON or disconnects the controlling cable with solenoid directional control valve, improve production effect
Rate.
Detailed description of the invention
Fig. 1 is hydraulic schematic diagram of the invention.
Specific embodiment
For the technological means for realizing the present invention, following further describes the present invention in conjunction with specific drawings.
As shown in Figure 1, a kind of clamping unit of transport raceway of the invention, including external oil route controller 9,
One hydraulic control one-way valve 1, the second hydraulic control one-way valve 2, third hydraulic control one-way valve 3, first hydraulic cylinder 6, second hydraulic cylinder 7, third liquid
Cylinder pressure 8, first contend with valve 4, second contend with valve 5, the oil inlet A1 of the external oil route controller 9 is connected separately with the first liquid
Control check valve 1, the second hydraulic control one-way valve 2, third hydraulic control one-way valve 3 and first contend with valve 4 and second contend with valve 5 pilot
Mouthful, the first hydraulic control one-way valve 1, the second hydraulic control one-way valve 2, third hydraulic control one-way valve 3 outlet respectively with first hydraulic cylinder 6, the
Rodless cavity one end connection of two hydraulic cylinders 7, third hydraulic cylinder 8, the oil outlet B1 of the external oil route controller is respectively with the
Rod chamber one end of one hydraulic cylinder 6, first contend with valve 4, second contend with valve 5 and the first hydraulic control one-way valve 1, the second fluid-control one-way
The pilot port connection of valve 2, third hydraulic control one-way valve 3, the first outlet for contending with valve 4 are connect with the rod chamber of second hydraulic cylinder 7, the
Two outlets for contending with valve 5 are connect with the rod chamber of third hydraulic cylinder 8.
Described first valve 4 and second that contends with contends with valve 5 using pilot control, and the adjusting pressure of its pilot control
It adjusts；Described second pilot control for contending with valve 5, which adjusts pressure and is greater than first, to be contended with valve 4；First hydraulic control one-way valve 1, second
